APPLIED BIOCHEMISTS Cutrine-Plus Granular Algaecide 12 lb | Algae Control for Ponds & Docks

Overview

APPLIED BIOCHEMISTS Cutrine-Plus Granular Algaecide is a granular copper-based treatment designed to address algae before it reaches the water surface. This granular algaecide helps reduce both filamentous and planktonic algae by delivering copper directly to the water column. It is especially effective for bottom-growing algae and for spot treatments along docks, beaches, boat launches, and fishing areas. The formula is built for practical use in a range of freshwater conditions, including hard water, with an emphasis on real-world results. Note that this listing includes one 12-lb container per package.

Used as part of an outdoor water care approach, Cutrine-Plus combines a double chelated copper formulation with 3.7% copper from ethanolamine complexes. The chelation helps keep copper available in the water and reduces precipitation that can occur with carbonate and bicarbonate buffers. This design supports algae management in varied environments, from quiet ponds to active shorelines.

Key benefits

• Visible reduction in algae growth 1-2 days after application
• Direct application to water affected by algae for targeted control
• Works in hard water; suitable for many freshwater settings
• Double chelated formula reduces copper precipitation; consistent performance in diverse conditions
• Includes one 12-lb container of Cutrine-Plus Granular Algaecide and Herbicide from Applied Biochemists

Practical uses and guidance

Ideal for bottom-growing algae and spot treatment along docks, beaches, boat launches, and fishing areas. The product is designed for localized application where algae are visible or accumulating, helping you focus treatment on problem zones rather than broad areas. When planning applications, consider wind and current patterns and target zones that display algae growth.

• Spot-treatment along shoreline structures to manage localized blooms
• Dock and boat-launch areas where algae can affect use and aesthetics
• Shoreline and fishing zones where algae can accumulate
